摘要： PURPOSE:To decide a position with high accuracy by a method wherein all receivable GPS signals from a GPS artificial satellite are received and all pieces of acquirable data are utilized for decision of the position. CONSTITUTION:For example, six receivable GPS signals are all received by a receiver 2, and four signals are formed as one set in an input part 6. That is to say, three-dimensional positions of 6C4=15 sets are found. Then, the value of the sum of DOP values indicating the degradation factor of respective positional accuracies and signal-to-noise ratios (SNRs) from five GPS artificial satellites excluding one GPS artificial satellite situated at a maximum angle of elevation out of six GPS artificial satellites is found regarding the three- dimensional positions of the 15 sets. Then, the value of the sum of the respective DOP values of the 15 sets and the SNRs is fuzzy-processed by a fuzzy processing part 7, and the reliability factor of the positions of the 15 sets is found. Then, the weighted average of the reliability of the positions of the 15 sets is found, and a final position is decided.

摘要： PURPOSE:To correct the degrading of position accuracy at a low cost without special equipment depending on selective utilizing property by extracting the diurnal component of changes in position from a data observed at a known fixed point to be stored together with time for use as correction value. CONSTITUTION:Signals received by an antenna 1 and a receiver 2 are demodulated to perform a position calculation with a arithmetic section 3. A satellite radiowave is received at a fixed known point for more than 24 hour and a difference between the fixed point positional information and a measured position obtained by receiving radiowaves to compute is determined to be supplied to a signal processing section 5. A position error data (diurnal component of positional changes) extracted with a processing section 5 is stored into a memory section 6 together with date and time data. When a receiver is used in a moving object such as ship later for position measurement, in computation with the arithmetic section 3, a memory data of the memory section 6 is used to determined a position by correction. As a satellite appears at the same position as that on the preceding day at a cycle of about 23 hour and 56 minute, it is advanced by 4 minute per day thereby enabling the correction of the data by the memory data four minute later back from the preceding day.

摘要： PURPOSE:To reduce the phenomenon, wherein the locus of the result of position measurement is discontinuous because of the fact that a satellite which can be utilized for the position measurement is changed, by the missing of the signal from the satellite. CONSTITUTION:In the position measuring operation in a GPS receiver, an offset value corresponding to an obtained satellite time is subtracted with respect to the satellite, for which the effective time is measured. Even if redundancy is present in the information amount as the number of the satellites, the position measuring operation, which is utilized in the position measurement including redundancy is performed. The radio-wave propagating time from the satellite, which is evaluated based on the position of the result of the position measurement is subtracted from the satellite time, from which the offset value is substracted. The difference between this value and the time of the position measurement obtained by the position measuring operation is obtained. The result is added to the corresponding offset value. A slight attenuation is added to the offset value, and the result is made to be the offset value in the next measurement.

摘要： PURPOSE:To make recognition of current position possible to be carried out by inputting an altitude data, being stored in correspondence with latitude and longitude, from a disc memory when it is judged that the current position is uncalculable, by a judging circuit. CONSTITUTION:A global positioning section 1 comprises a GPS receiver 7 receiving signals from a required satellite, a signal processing section 8 for measuring the current azimuth of a mobile based on the received signal and outputting an azimuth signal corresponding to the current azimuth, and a CD-ROM 17 storing altitude data in correspondence with latitude and longitude. When a receiving condition judging circuit/code data generation indication circuit in the signal processing section 8 judged that a value representative of deterioration of accuracy in two-dimensional positioning is lower than a set value B although a value representative of deterioration of accuracy in three-dimensional positioning is higher than a set value A, a receiver current position calculating circuit reads out altitude data corresponding to coordinate data of latitude and longitude from the CD-ROM 17 and then calculates the coordinates of receiving point based on the altitude data.

摘要： PURPOSE:To provide a GPS navigation apparatus foe vehicle, wherein the abnormal positioning (the erroneous positioning) of a GPS can be always detected. CONSTITUTION:A receiver 1 is installed on a vehicle, a CD-ROM 4 is connected to a microcomputer 2, and map information inclusive of altitude information is stored in the CD-ROM 4. The microcomputer 2 detects the altitude of the receiver 1 from signals, from a plurality of GPS satellites S1 to S4, which have been received by the receiver 1, and it computes the altitude of the receiver 1 by the CD-ROM 4 corresponding to the latitude and the longitude of the receiver 1 from its latitude and its longitude by the signals, from the plurality of GPS satellites S1 to S4, which have been received by the receiver 1. Then, the microcomputer 2 computes the deviation between the altitude of the receiver 1 by data from the satellites S1 to S4 and the altitude of the receiver 1 by the CD-ROM 4, and, when the deviation amount exceeds an allowable value, the microcomputer judges that an abnormality exists.
